An Empirical Study of a Repeatable Method for Reengineering Procedural Software Systems to Object- Oriented Systems
This paper describes a repeatable method for reengineering a procedural
system to an object-oriented system. The method uses coupling metrics to assist a domain
expert in identifying candidate objects. An application of the method to a simple program
is given, and the effectiveness of the various coupling metrics are discussed. We perform
a detailed comparison of our repeatable method with an ad hoc, manual reengineering
effort based on the same procedural program. The repeatable method was found to be
effective for identifying objects. It produced code that was much smaller, more efficient,
and passed more regression tests than the ad hoc method. Analysis of object-oriented
metrics indicated both simpler code and less variability among classes for the repeatable
method
